Important Information Before using the backup sensors, make sure you read and understand the operation and limitations of the system as discussed throughout this manual. The backup sensors are designed to provide an audible sound when they detect large stationary objects while the vehicle is moving in reverse at low speed. However, the system may not detect all objects depending on their size, shape, and location. Even with the backup sensors, the driver is still responsible for making sure the path is clear when driving in reverse. 4 2006 American Honda Motor Co., Inc. - All Rights Reserved.
How the Backup Sensors Work Backup Sensors The sensors are ready for operation when the shift lever is moved to the reverse position. The sensors operate by emitting ultrasonic waves. They calculate the distance between the rear bumper and an obstacle by measuring the time the ultrasonic waves take to reach the sensor after being reflected by an obstacle.

How the Backup Sensors Work The sensors are designed to give you an audible signal when the rear bumper is approaching an obstacle. Corner Sensors: The audible signal has three sounds: Sound Corner Sensors Center Sensors Fill Pattern Slow intermittent beeps Quick intermittent beeps Continuous beep Within 2.0 feet (60 cm) Within 1.5 feet (45 cm) Within 1.0 foot (30 cm) Within 4.9 feet (150 cm) Within 3.3 feet (100 cm) Within 1.6 feet (50 cm) 1234567890 1234567890 Center Sensors: 4709010Y 6 2006 American Honda Motor Co., Inc. - All Rights Reserved.
How the Backup Sensors Work The sensors detect the closest rear obstacle. The system can be turned on/off by operating the switch of the buzzer. BUZZER SWITCH RIGHT REAR PILLAR PANEL ON In this example, the corner sensor detects the side wall. OFF The sensors may not detect the rear bumper of tall vehicles. 6612390B 2006 American Honda Motor Co., Inc. - All Rights Reserved. 7
Limitations The sensors may not work if the obstacle is an odd shape or made of material that does not reflect ultrasonic waves. The sensors may not work if the ambient air temperature is below -4 F (-20 C) or above 122 F (50 C). Examples: POLE RECTANGULAR LUMBER CARDBOARD CARTON SMALL TREE BICYCLE TIRE 4202020Y The audible signal may sound a warning even if there is no obstacle behind the vehicle: Water frozen on the sensor CURBSTONE SOFT SNOW AND OTHER ABSORBENT OBJECTS WIRE, ROPE, AND NET FENCE 4202030Y 4202040Y 8 2006 American Honda Motor Co., Inc. - All Rights Reserved.
Limitations The audible signal may sound warning even if there is no obstacle behind the vehicle: Sensors clogged with snow, dirt or mud When the vehicle is equipped with a highpower radio and antenna 4202050Y The sensors may sound continuously under the following conditions: When driving on rough surfaces or gravel roads or in grass, or when stopped on a hill 4202060Y When detecting loud noises such as a vehicle horn, a motorcycle s engine, or air brakes When driving in rain or melted snow 2006 American Honda Motor Co., Inc. - All Rights Reserved. 9
Operation Before using the backup sensors, become familiar with the types of sounds in relation to the distances between the sensors and the obstacle by actually backing your vehicle into a garage or parking space. Also confirm the obstacle detecting range of each backup sensor. 1. Apply the parking brake. 2. Turn the ignition switch to ON (II), but not start the engine yet. ON 4. With one of the doors open, check that the audible signal sounds by slowly bringing the palm of your hand close to each sensor as described: For the corner sensors: From 2.0 feet (60 cm) For the center sensors: From 4.9 feet (150 cm) Confirm that the sound of the corner sensors is different from that of the center sensors. 3. Move the shift lever to reverse. Confirm the obstacle detecting range of each sensor. 4202080Y 10 2006 American Honda Motor Co., Inc. - All Rights Reserved.
Operation 5. Check that the intermittent warning beeps become quicker as you bring the palm of your hand closer to the sensor. For the corner sensors: About 1.5 feet (45 cm) For the center sensors: About 3.3 feet (100 cm) 6. Check that the intermittent warning beeps change to a continuous beep as you bring the palm of your hand closer to the sensor. It may stop making noise or emit intermittent beeps if you move your hand closer too quickly. For the corner sensors: About 1.0 foot (30 cm) For the center sensors: About 1.6 feet (50 cm) 7. The sound volume can be adjusted by turning the dial of the buzzer. MIN BUZZER DIAL MAX RIGHT REAR PILLAR PANEL 6612400B 8. Turn the ignition switch to OFF (0). 2006 American Honda Motor Co., Inc. - All Rights Reserved. 11
Daily Inspection 1. Turn the ignition switch to ON (II), and apply the parking brake. 2. Depress the brake pedal, and move the shift lever to the reverse position. Check that the audible signal sounds for about one second. The sensors are normal if the audible signal sounds for about one second. If the audible signal keeps sounding, this is an indication that the sensors are frozen or clogged with mud, dirt, etc. If the sensors are clean but keep sounding, there is an abnormality in the circuit. See your Honda dealer when possible. Be careful not to confuse the sound of the sensors with those of other components or systems. 12 2006 American Honda Motor Co., Inc. - All Rights Reserved.
Caring for the Backup Sensors Wipe the sensors clean with a clean cloth, or flush with low-pressure water if they are clogged with mud and dirt. Do not spray high-pressure water against the sensors. LOW-PRESSURE WATER 4202090Y HIGH- PRESSURE WATER (Do not use.) 4202100Y 2006 American Honda Motor Co., Inc. - All Rights Reserved. 13
Troubleshooting Perform the following checks if the audible signal does not sound when the vehicle is approaching an obstacle. Symptom Clogged sensor with snow or mud Frozen sensor Extended parking in cold weather or under blazing sun Remedy Wipe with a clean cloth or flush with low-pressure water. Melt with lukewarm water The backup sensors may not work if the outside air temperature is below -4 F (-20 C) or above 122 F (50 C). Take your vehicle to your Honda dealer if you encounter either of these problems: The audible signal sounds continuously when the shift lever is in the reverse position, and the sensors are not frozen or clogged with snow or mud. The audible signal does not sound when the shift lever is in the reverse position. Ask your Honda dealer for advice if the trouble persists. 14 2006 American Honda Motor Co., Inc. - All Rights Reserved.
Troubleshooting Troubleshooting With Beeps When you turn the ignition switch to ON (II), and the backup sensor signal sounds more than once, there may be a problem with one of the sensors. Corner Sensors Two fast beeps: right sensor is faulty. Three fast beeps: left sensor is faulty. Four fast beeps: right and left sensors are faulty. Center Sensors Two slow beeps: right sensor is faulty. Three slow beeps: left sensor is faulty. Four slow beeps: right and left sensors are faulty. 2006 American Honda Motor Co., Inc. - All Rights Reserved. 15
